LYMAN XV. MERRIAM, OF WINOHENDON, MASSACHUSETTS, ASSIGNOR OF ONE-HALF TO JOHN HANCOCK, OF SAME PLACE.

SHUTTER-HINGE.

SPECIFICATION forming part of Letters Patent No. 288,834, dated November 20, 1883.

Application filed May 17. 1883. (No model.)

To all whom it may concern:

Be it known that I, LYMAN XV. MEERIAM,

a citizen of the United States, residing at Ninchendon, in the county of \Vorcester and State of Massachusetts, have invented certain newandusefullmprovementsinVVindowBlind Hinges; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of I reference marked thereon, which form a part of this specification.

This invention relates to hinges for windowblinds; and it consists in the construction and arrangement ofpa-rts, as hereinafter more fully described and claimed.

In the annexed drawings, illustrating the invention, Figure 1 is an edge view of a window-blind turned at a right angle with the window-casing and parallel with the wall of the building, showing my improved hinges in position. Fig.2 is a plan or top view of the same. Fig. 3 shows the parts of the hinge detached. Figs. 4 and 5 are sectional details, showing the parts connected. Figs. 6 and 7 are modifications.

Like letters indicate like parts in the several views.

The hinge consists of a part, A, for attachment to the window'casing B, and a part, 0, for attachment to the blind D, as shown in Figs. 1 and 2. The parts A and O are made of cast metal in the form shown in Fig. 3.

The stationary part A of the hinge is formed with a body, a, having prongs'b 7), preferably of unequal length, as shown, and a flanged portion, 0, in which is formed an eye, (2, having an elongated portion or notch, d, as shown. By means of the prongs b b the stationary part of the hinge may be attached to the windowcasing B, into which the prongs are driven, as shown in Figs. 1 and 2.

The movable part 0 of the hinge consists of the portions e and fiarranged at a right angle to each other and connected by a rib, g. In the vertical portion or flange e of this movable part of the hinge are formed screw-holes h h,

for the passage of screws, by which this part of the hinge is secured to the window-blind. On the under side of the horizontal portion or flange f is cast a pin or pintle, 2', having at its lower end in front a projection or lug, k, that is capable of passing through the elongated 5 5 portion of the eye (I when the window-blind is turned at a right angle with the window, as shown in Fig. 5; but when the blind is turned parallel with the wall, either opened or closed, as shown in Fig. 4, the lug 76 engages beneath the flange c and effectually prevents disconnection of the parts of the hinge.

As the lug k is in line with the long diameter of the eye (I only when the blind is at aright angle with the window, it will be seen that the blind can be unshipped only when turned to this position. It will be observed, however, that in opening and closing the blind the lug kwill coincidewith the elongated portion of the eye 01 only for an instant, and the liability of throwing the blind from the stationary part of the hinge,while opening or closing, is thus practically avoided.

It will be seen that when the part 0 of the hinge is attached to the blind, the pin i is in 7 the central vertical line of the blind-edge, which obviates the necessity of making the stationary part or" the hinge so long as is usually required, and consequently the greatest strength and durability are combined with compactness of structure.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

A hinge consisting of the part A, having drive=pr0ngs b b and an eye, (I, provided with notch d, and the part 0, having flanges cf, rib g, and a pin, 43, provided with lug k, substantially as described.

.In testimony whereof I affix my signature in 0 presence of two witnesses.

LYMAN w. MERRIAM.
